Ultrasound, Ct-scan, and laparoscopy, diagnostic observations on non-palpable testis

To evaluate the comparative diagnostic efficacy of Ultrasound, CT-Scan, and Laparoscopy in the diagnosis of non-palpable undescended testes in pediatric patients. Comparative study. Surgical and pediatric surgical department of B V Hospital [QAMC] Bahawalpur and Allied Hospital Faisalabad. From April 2006 to April 2007. A total forty boys with non palpable testis were subjected to Ultrasound, CT-Scan and diagnostic laparoscopy in a period of one year. The patients above 12 years and with cardiovascular anomalies were excluded from the study. Laparoscopy was performed under general anesthesia and findings were compared with Ultrasound and CT-Scan. Sensitivity and specificity of each were calculated. Diagnostic accuracy of Ultrasound was 25%, CT-Scan was 64% and Laparoscopy was 100%. Sensitivity was found to be 20%, 63% and 100% and specificity was 10%. 50% and 100% for Ultrasound, CT-Scan and Laparoscopy, respectively. Diagnostic laparoscopy is far more superior as compared to Ultrasound and CT-Scan in the diagnosis of non palpable testis

Laparascopic management of impalpable cryptorchiol testis

Laparoscopy has been widely used in the diagnosis and treatment of impalpable testises. This study was done to report the first experience of the use of laparoscopy in impalpable testises in the Mashhad university of medical sciences [MUMS]. During 6 years, 43 patients with UDT were treated. In those were no evidence of existence of gonad in physical examination and ultrasonography, laparoscopy was done by the 5 [mm] [0 [deg]] lens. Position of testis, complications of operation and duration of admission in hospital was recorded. In the 13 patients from 43 patients [30.23%] testis was not palpable in the inguinal canal. Also ultrasonography didn't detect the existence of testis.Therefore, laparoscopy was used. Average age of patients was 11.88 +/- 8.38 years. In 3 patients small remnant of testis was seen. Two patients had no testis. In 8 patients, normal gonads were seen that the treatment was done. No severe or mild complications were seen. All of the patients except one were discharged 24 hours after operation. Our study showed that laparoscopy is a beneficial and safe instrument to correct diagnosis in impalpable testises and in some situation prevents from an unnecessary exploration of inguinal region and laparotomy. Also in patients that previous exploration was not beneficial for them causes a correct diagnosis
